Pull ARM DT updates from Arnd Bergmann:
"This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit
respectively. There are lots of cleanups and additional hardware
support for platforms we already support based on SoCs from Renesas,
ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and
other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
- The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone
platform, usually paired with an external 5G modem. So far we only
support the Qualcomm SM8150 MTP reference platform, but no actual
products.
- For the slightly older Qualcomm platforms, support for several
interesting products is getting added: Three laptops based on
Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix
630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630)
and several phones based on the older Snapdragon 410/MSM8916
(Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed"
aka Wileyfox Swift).
- Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
- Allwinner V3 is a repackaged version of the existing low-end V3s
chip, and is used in the tiny Lichee Pi Zero plus, also added here.
There is also a new TV set-top box based on Allwinner H6, the Tanix
TX6, and the eMMC variant of the Olimex A64-Olinuxino development
board.
- NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC
family, similar to the i.MX8M Mini. As usual, there is a large
number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML,
SolidRun Hummingboard Pulse baseboard and System-on-Module,
Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion
PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the
Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
- In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
- Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from
their set-top-box line and smart speaker with newer CPU and GPU
cores compared to their predecessors. Both are now also supported
by the Khadas VIM3 development board series, and the dts files for
that get reorganized a bit to better deal with all variants.
Another board based on SM1 that gets added is the SEI Robotics
SEI610.
- There are a handful of new x86 and Power9 server boards using
Aspeed BMC chips that are gaining support for running Linux on the
BMC through the OpenBMC project: Facebook
Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably
these are still new machines using SoCs based on the ARM9 and ARM11
CPU cores, as support for the new Cortex-A7 based AST2600 is still
ramping up.
- There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the
low-end RK3229 chip, while the two AOpen products Chromebox Mini
(Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for
commercial settings(digital signage, PoS, ...).
- One more single-board computer based on the popular 64-bit RK3399
is added: the Leez RK3399 P710"
